Project plan The following project plan indicates activity times in days:

Note: Under normal conditions, the project team will be able to finish Activity A in 7 days with a TOTAL cost (for the entire 7 days) of $7,000. Under exceptional conditions when the project team must crash (or expedite) Activity A, it will take 6 days to finish with a TOTAL cost (for the entire 6 days) of $8,000.

4.1. What is the critical path?

4.2. How many days will the project take to complete?

4.3. To shorten the project by 4 days, which tasks would you shorten using the minimum cost method, and what would the final total project cost be?
